A switch is provided for selectively routing digital information packets received from at least first and second external sources to at least first and second external destinations. At least one of the first sources generates an information packet including a datum (or a request therefor) and a corresponding descriptor. First and second routing interconnects have inputs for receiving packets from respective sources and outputs for transmitting packets to respective destinations. The interconnects are also coupled for transferring packets between one another. Directories within the interconnects store descriptors corresponding to data associated with the first destination, as well as requests routed from the other interconnect. A controller routes packets based on the correspondence, or lack thereof, between the descriptor in that packet and an entry signal allocated to corresponding directory. <IMAGE>
